• High river temperature reduces survival of sockeye salmon (Oncorhynchus nerka) approaching spawning grounds and exacerbates female mortality (2012, background): “It is thus not surprising that fish are particularly vulnerable to mortality during periods of high water temperatures (Davis 2002).”
• FISH Out of WATER: How Much Air is Too Much? (2015, background): “It may be possible to adjust fishing practices to reduce catch size (e.g., trawl or soak times), thereby reducing numbers of nontarget species as well as handling time on deck, without decreasing catch per unit effort (Davis 2002).”
• Short-term survival of discarded target fish and non-target invertebrate species in the “eurocutter” beam trawl fishery of the southern North Sea (2014, background): “, 1990), catch composition and towing speed affect fishing induced stress, injuries and survival (Davis, 2002), differences in survival between trawls with tickler chains and chain mats are expected (e.”
• Simulated fishing experiments for predicting delayed mortality rates using reflex impairment in restrained fish (2007, background): “Juvenile fish were towed in a net that simulated capture in the codend of a trawl to produce a range of mortalities based on results of previous studies in this laboratory (Olla et al., 1997; Davis et al., 2001; Davis, 2002 ).”
• Vulnerability of oceanic sharks as pelagic longline bycatch (2014, background): “However, the interaction among water temperatures, fishery capture stress and survival is poorly understood, particularly in bycatch scenarios for marine fishes (Davis, 2002; Gale et al., 2013).”
• The understudied and underappreciated role of predation in the mortality of fish released from fishing gears (2014, background): “fins, opercula), all of which can lead to fungal infections (Davis 2002; Baker and Schindler 2009).”
• Discards, hooking, and post-release mortality of porbeagle (Lamna nasus), shortfin mako (Isurus oxyrinchus), and blue shark (Prionace glauca) in the Canadian pelagic longline fishery (2016, background): “As a result, some sort of tag–recapture or telemetry programme is required to properly estimate the post-release mortality rate of discarded fish (Davis, 2002; Pollock and Pine, 2007; Skomal, 2007).”
• Estimating the odds of survival and identifying mitigation opportunities for common bycatch in pelagic longline fisheries (2009, background): “We recognize sub-lethal capture effects increase post-hooking mortality (e.g., Borucinska et al., 2002; Davis, 2002; Horodysky and Graves, 2005).”
• Freshwater Commercial Bycatch: An Understated Conservation Problem (2011, background): “Many of these factors are intuitive: anoxia, air exposure, and handling time each should increase stress and mortality in fishes (Davis 2002).”
• Estimating Collateral Mortality from Towed Fishing Gear (2006, background): “As with escapees, various interacting factors contribute towards mortalities (Davis 2002).”
• Effects of river temperature and climate warming on stock‐specific survival of adult migrating Fraser River sockeye salmon (Oncorhynchus nerka) (2011, background): “Second, stress-related mortality associated with capture is exacerbated by warm temperature (Wilkie et al., 1996; Kieffer, 2000; Davis, 2002), and this likely occurs because warm temperature enhances baseline stress levels.”
• The role of temperature in the capture and release of fish (2013, background): “A limitation of this approach is that in addition to physiological stress and exercise, fish sustain injuries from escaping or being released from fishing gears (Chopin and Arimoto 1995; Broadhurst et al. 1999; Cooke and Hogle 2000; Davis 2002; Bartholomew and Bohnsack 2005; Arlinghaus et al. 2007).”
